Science and Motivation

This workshop aims to provide an opportunity to exchange views and share information about the current status of observations and theoretical research on a wide range of aspects concerning the formation of astronomical objects. Moreover, it also serves as interim report by students in our research group who are working on dissertations. This year, the meeting will be held over two days, November 17 and 18. we plan to have a hybrid format consisting of on-site participation in the CCS workshop room and online participation via Zoom.
